Fender P/N 053493 manual Tube Replacement, Troubleshooter’S Checklist, Covering Care

TUBE REPLACEMENT

Tube life varies depending upon

playing style and application with

power tubes having a much shorter

life than pre-amp tubes which can last

for years. For continued optimum performance from your amplifier, the tubes should ONLY be replaced with the same type

tubes as specified on the tube location label inside the cabinet.

A simple way to check if the tubes are worn is to replace the set in your amp with your spare set. (You do carry spare tubes and fuses, don't you?)

When changing the tubes, ALWAYS unplug the amplifier and remember THE TUBES ARE HOT! Either wait for the tubes to cool or use an insulated oven mitt to remove them from your amplifier.

•First, replace the OUTPUT tubes in the amplifier and listen.

•Next, re-insert the original output tubes. Replace the PRE-AMP tubes and listen.

•Finally, try replacing both the OUTPUT and PRE- AMP tubes and listen.

If there is a marked improvement in the tone of your amp at any point in this procedure, leave the new tubes in your amp and purchase another spare set.

Your Vibro-King's tube compliment consists of:

•Two 5881 Tubes (part #099-5090-000),

•Five 12AX7A Tubes (part #099-5091-000),

•One Special Design 6V6 Tube (part #099-5093-000).

TROUBLESHOOTER’S CHECKLIST

If the amp is set up but does not function, check the following items:

• Is the amp power cord properly plugged into an electrical outlet?

•Is there power to the outlet?

•Is the fuse blown?

•Is the speaker(s) properly connected to the amplifier?

•Is the amp on standby?

•Are the amplifier VOLUME, TREBLE, MID and BASS controls above 0?

•Is the instrument volume control turned up?

•Is the instrument plugged into the amplifier?

(Eliminate any effects pedals and try another guitar cord.)

Check under all tube covers to see if the tube filaments are glowing.

If, after checking all of the above, your amplifier is not performing correctly, consult your nearest authorized Fender service center.

COVERING CARE

Your Vibro-King is covered in genuine Tolex for long life and lasting good looks. To clean the Tolex covering, use a sponge and a light soapy water solution. Avoid spilling liquids on the operating surfaces, grill, volume and

tone controls, switches and speakers. ALWAYS unplug your amplifier before cleaning or approaching it with fluids.
